Map: Baby Names Show Regional Differences, But Many Similarities

From Oregon to Maine -- and Alaska and Hawaii as well -- Emma was the most popular name for girls born in 2014 in 22 states. Olivia was the most common name in 15 states.

Emma and Olivia will probably be sitting through the ceremony next to Liam, Noah and/or William, which were the most popular names for boys in 37 states combined.

There were some outliers.

The most popular name for girls in both North and South Dakota was Harper (Emma and Olivia made the top 5 in both states). Isabella was the most popular name for Florida girls, and Elizabeth won in the District of Columbia.

Sophia, a very popular name for girls over the last few years, still has some adherents: She was the most popular name in California, Arizona, New York, New Jersey, Delaware and West Virginia last year.

Ava was popular in a few southern states.

Names for boys were also regionalized. Liam was the most popular name in 16 states, almost all of them north of the Mason-Dixon line.

On the other hand, William was the most popular name for boys in 12 states, the bulk of which are in the south.

Mason, the most common name for boys in Connecticut in 2014, was also the winner in Rhode Island, Pennsylvania, West Virginia, Wisconsin, Arkansas and Louisiana. Noah was popular in the south and west.

Massachusetts, New Jersey, Wyoming and Minnesota stand alone. In Wyoming, the most popular boys' name was Jackson -- which presumably was influenced at least in part by the swanky ski town of the same name on its western border.

In Massachusetts, Benjamin was the most popular. New Jersey went with Michael, the most popular name for boys of the last 75 years.
